• If the caller is not in the caller resolution table, and RADIUS is configured, a

request is sent to the RADIUS server for authentication.

ISDN Services

A router with built-in ISDN capability is a TE1 device, which is an

ISDN-compatible device. This means that the router provides the S/T interface,

which defines the boundary between the user and the network. (The ARN also

provides the U interface, which includes an integral NT1 interface.) The NT1

interface defines the point at which the service provider’s wires terminate at your

site.

For BRI service, the S/T interface follows the standards outlined in ITU-T

recommendation I.430, the physical layer protocol that defines the S/T interface.

For PRI service, the interface follows ITU-T recommendation I.431.

You have an S interface only if an NT2 device is present. An NT2 is a switch at

your site that connects your TE1 and TE2 equipment to the network.

The following sections explain ISDN operation on your router.

Note:

Do not configure the remote router in the caller resolution table. If you

do, the local router, which is the RADIUS client, will not access the

vendor-specific attributes.
